Abstract

The invention belongs to the technical field of preparation of a cleaning agent for a fine metal mask (FMM), and particularly relates to a cleaning agent for an OLED mask and a cleaning process thereof. The cleaning agent comprises the following components, in percentage by mass, 20%-50% of alcohol ether solvent, 20%-50% of polar non-proton solvent, 1%-10% of a fluorine-containing nonionic surfactant, and 10%-30% deionized water; the fluorine-containing nonionic surfactant has a structural formula seen in the specification, and n is a natural number between 8 and 14; and the cleaning solutionprovided by the invention can quickly and effectively clean and remove RGB photochromic dye attached to the FMM in the vapor deposition process, is easy to clean, does not remain, and effectively improves the cleaning efficiency of the FMM.

Description

technical field [0001] The invention belongs to the technical field of cleaning agent preparation for fine metal masks, and in particular relates to a cleaning agent for OLED masks and a cleaning process thereof. Background technique [0002] Flat panel display (Plat Panel Display, FPD) is one of the most important optoelectronic products at present, the current mainstream flat panel display can be divided into liquid crystal display (Liquid Crystal Display, LCD) and organic light emitting diode (Organic Light Emitting Diodes, OLED). Among them, OLED displays have the characteristics of self-illumination, wide color gamut, wide viewing angle, short response time, high luminous efficiency, low operating voltage, lighter and thinner, and can produce large-size and flexible panels, and the manufacturing process is simpler. It is recognized by the industry as a new generation of display that may replace LCD. [0003] At present, the relatively mature OLED display manufacturing ...
